FREDERICK L. IIEUGHES, OF ROCHESTER, NEW YORK.

SIDEWALK-LIGHT.

Specification of Letters Patent.

Application iledAug'nstklZ, 1911. Serial No. 643,809.

To all whom it may concern:

Be it known that I, FREDERICK L. Hnucnns, a citizen of the United States, and resident of Rochester, in the county of Monroe andState of New York, have invented certain new and useful Improvements in Sidewalk-Lights, of which the following is a specification.

This invention relates to side-walk lights of the type in which glass prisms or lenses are mounted in a frame-work built up of interlocking iianged bars. y

The object of the invention is to produce a frame-work which shall be rigid, but inexpensive in construction and easy to set up, and particularly a frame of this kind which affords seats extending throughout the periphery of the lenses so as to produce a water-tight construction in which a broken lens can be readily replaced in a manner to insure against leakage.

In the drawings z-Figure 1 shows in perspective the construction of the frame in which the glass lenses are supported; and F ig. 2 is a cross-section on the line 2 2 of Fig. l, with a glass lens in place.

The frame is composed of a system of main bearing bars l interlocked with crossbars 2, all made of iron or other suitable material in lengths convenient for handling and shipping, which can readily be cut up into the lengths required. The main bearing bars l have on each side medial flanges 3, 3, and are recessed as shown at l to receive the cross-bars 2 at regular intervals corresponding to one of the surface dimensions of the glass lens which they are to receive. The cross-bars 2 are T-shaped in form, and have recesses 6 in their flanges 5, 5 that extend up into the bars, at regular intervals corresponding to the other surface dimension of the glass lens. Thus the main bearing bars and the cross-bars are adaptedV to interlock and form between them spaces of uniform size (squares being represented in the drawing), with the flanges 5, 5 of the cross-bars overlying the flanges 3, 3 of the main bearing bars. This construction is very strong notwithstanding the fact that the bars are cut into to form the recesses, since in each space the flanges of each crossbar rest on flanges of one of the main bearing bars.

The glass lenses rV correspond in surface dimensions with the spaces formed as aforesaid between the bars, and are thick enough to rest on the lower flanges 3, 3 of the main bearing bars l and at the same time project some distance above the top of the frame, being also recessed as indicated at 8-8 on each side so as to overlie the flanges 5, 5 of the cross-bars 2. lVhen the structure is rst set up, the upper edges of the cross-bars 2 are slightly below the top of the main members 1. The edges of the slots Ll are then struck down over the bars 2, as indicated at 9 in Fig. 2, to prevent the cross-bars from being misplaced or loosened. The lenses are then dropped in place as usual and the spaces between them are filled with cement as usual, down to the flanges 5, and the cement is leveled off at the top.

l. In a sidewalk light, the combination of parallel main bars, each of said bars hav- 'ing a relatively wide vertical flange and a narrow transverse side-supporting and stiffening iiange on the opposite sides thereof adjacent the neutral axis thereof, the main bars being solid from the bottom up to a line above and parallel to the transverse flanges, cross-bars interlocked or halved with said main bars, said cross-bars having supporting iianges on each side thereof resting on the transverse flanges of the main bars, said main bars and said cross-bars forming pockets between them having inwardly projecting flanges at the bottom thereof, glass lenses supported by said fianges and projecting above said bars, and a cement filler filling in the spaces between said lenses and said bars.

2. In a sidewalk light, the combina-tion of parallel main bars, each of said bars having a relatively wide vertical flange and a narrow transverse side-supporting and stiffening fiange on the opposite sides thereof adjacent the neutral axis thereof, the main bars being solid from the bottom up to a line above and parallel vto the transverse flanges, cross-bars interlocked or halved with said main bars, said cross-bars having supporting flanges on each side thereof resting on the transverse flanges of the main bars, said main bars and said cross-bars forming pockets between them having inwardly proratentea .fune 25, 191.2.

jeetng flanges at the bottom thereof, glass bars may be battered down at said recesses lenses supported by said flanges and proto lock the cross-bars in said recesses.

normally slightly below the tops of said C. S. DAVIS,
